◆ setBlockSize()

void QBenchmarkTestMethodData::setBlockSize ( int split = 32)

Split up iterations into a statistically useful number of blocks.

Record data in blocks. split is the desired number of blocks which is a power of 2 like iterationcount. As long as split is below 32 we treat each iteration as a block. When split is greater than 32 split becomes a divisor for iterationcount. The goal is to reduce overhead from measurements while calculating variance. The default split 32 should be sufficient to get stable block-variance, from which the per-iteration variance (estimator) can be computed by dividing by the block size.
